Document Summary
All laws of nature are the same for observers moving in an arbitrary way relative to one another. Makes the curvature of space a physical variable, describing gravity. Special relativity says the law of physics were the same for everyone moving the same speed. Consider a rocketship so far out in space that gravitational forces are negligible. Einstein: no experiment performed in one place can distinguish a gravitational. The astronaut cannot distinguish if they are in an accelerating eld or at rest. **if bob shines a light in his accelerating rocket, the light appears to fall towards the. Like everything else, the path of light rays must bend in a gravitational eld. How is there a gravitational eld inside the rocket that isn"t experienced by anyone else: gravity is acceleration. Because the rocket is accelerating it creates the effect of a gravitational. Not much! a distance of 10m it might change equivalent to the size of a nucleus.
